Can't Purchase anything in App Store, Additional Security Information Needed
I am trying to make a purchase from the App Store in Snow Leopard 10.6.8, but can't make any purchases. When I try to purchase, I get the message, "Additional security information is needed. To use this Apple ID you must first login to the my info web page then provide additional security information." But when I click on Update Security Info, it brings me to a page at https://myinfo.apple.com/ but the page will not load, and it says that Safari can't establish a secure connection to the server. I have also tried it in Firefox and it does not work there either.
I went to the Apple Store online, and updated my account info with the proper credit card and information, but it has not helped. What is going on here.
This is for my bosses account and not my account, and we need to purchase some software for this machine, but are completely unable.
Any help would be appreciated.
